®  Color  is  in  light  ®  Isaac  Newton  discovered  how  light  is  broken  up  when  put  through  a  prism  

Red

Violet

Orange

Green Blue

Yellow

®  When  light  hits  an  object  some  light  is  absorbed  while  other  light  is  reflected  

®  This  reaction  creates  color  ®  When  all  light  rays  are  absorbed  the  object  is  black  ®  When  all  light  rays  are  reflected  the  object  appears  white  

®  When  one  ray  is  reflected  (ex.  Red)  the  object  will  appear  that  color  

®  Our  eyes  are  made  up  of  rods  and  cones  ®  There  are  three  types  of  cones  in  our  eyes  that  allow  us  to  see  all  colors  

®  Rods  help  us  see  in  dim  light  

®  Having  the  three  cones  is  called  trichromats  ®  The  cones  are  either  red,  blue,  or  green  

®  All  hues  can  be  created  by  mixing  these  three  colors  

®  Hue:  a  color  (red,  blue,  green,  etc.)  ®  Light  is  projected  into  the  retina  and  hits  the  rods  and  cones,  the  retina  sends  signals  to  the  optic  nerve,  the  image  is  projected  upside  down,  and  the  brain  flips  it  

Color  Blindness  • Color Blind: The inability to perceive differences between some of the colors that others can distinguish • It is typically genetic, but can be caused from nerve or brain damage • It is more common in males than females • Three types: monochromacy (total color blindness), dichromacy (one of the three basic color mechanisms is absent), anomalous trichromacy (one of the three color mechanisms is impaired

Color  Blind  Test  

Color  Blind  Test  

®  Primary  Colors:  red,  yellow,  blue  ®  Secondary  colors:  orange,  green,  purple  ®  Complementary  colors:  blue  and  orange,  red  and  green,  yellow  and  purple  

®  Tertiary  colors:  red-­‐orange,  yellow-­‐orange,  blue-­‐green,  etc.    

® Tints:  created  when  white  is  added  to  a  color  

® Shades:  created  when  black  is  added  to  a  color  

®  Using  primary  colors  ONLY  fill  in  the  color  wheel  worksheet  

®  You  will  be  using  primary  colors  to  create  secondary  and  tertiary  colors  

®  Mix  the  colors  50%  to  get  the  most  accurate  color  

®  Do  not  get  more  paint  than  you  need!  ®  Be  neat,  drag  the  edge  of  the  brush  along  the  edge  of  the  shapes  to  get  a  clean  line
